Generates an FPF-compliant OpenTelemetry Span mapped to U.Work.
This skill implements FPF Pattern A.15.1 (U.Work) by mapping execution units to OpenTelemetry Spans. It ensures "Lawful Telemetry" (G.12) by strictly adhering to the 4D Anchor schema.
You must generate a valid U.Work record formatted as an OpenTelemetry Span structure.
You must include the following attributes in the span. IF a value is missing, you must either derive it or explicitly label it as UNKNOWN (do not omit).
| FPF Anchor | OTel Attribute | Value Requirement |
|---|---|---|
| Spec | fpf.spec_ref | URI of the Method being executed (e.g., ). |
method:PlanTask@v1| Performer | fpf.performer_ref | URI of the Role/Agent (e.g., role:Assistant@run-1). |
| Context | fpf.context_ref | URI of the Bounded Context (e.g., ctx:AgentFS-Experiment-C1). |
| System | fpf.system_ref | Identity of the runtime system (e.g., sys:MacBookPro-M3). |
| Pins | fpf.edition_pins | JSON string of version pins. |
If the work involves derived metrics, include them as attributes:
fpf.outcome.class: One of Success, Failure, Aborted.fpf.outcome.rubric_score: (Optional) Integer 1-5.Return the JSON representation of the Span, including name, start_time, end_time, and attributes.
